These designations are designed to rate each player's Fantasy value for the current week only and have no bearing on his value for the season as a whole.

Any player dealing with injury will have the injury listed in parentheses after his name. His condition will most definitely influence his category designation for the week.

Any players not appearing on these lists are presumed to be below "don't bother" status and are obvious sits in Fantasy.

Catcher

Ryan Doumit has been one of the hottest catcher-eligible players in Fantasy over the last couple weeks, but unfortunately, he left Wednesday's game with a strained calf -- an injury severe enough that the Twins initially planned to put him on the DL. For now, they've decided to delay that move, hoping that Doumit shows improvement within a few days, but knowing how slow calf injuries are to heal, he could ultimately still wind up on the DL. He didn't return to the lineup over the weekend, so you should plan to sit him in Fantasy.

Worth a second look: Jonathan Lucroy, BrewersLucroy isn't a big name at the catcher position, but right now, he's too hot to ignore, batting .397 (23 for 58) with a .978 OPS over his last 16 games. Of course, one little hot streak isn't enough to make him a viable mixed-league option, but when you consider the Brewers are facing four lefties this week, against whom he has a career .311 batting average and .875 OPS, you have to think he has more good times ahead. If you've been scavenging for a catcher all season, Lucroy should at least meet your need in the short term.Approach with caution: Russell Martin, YankeesIt's just not getting any better for Martin, who entered the season as one of the top 12 catchers in Fantasy but is now batting just .170 on the season after a recent 3-for-32 (.094) stretch. The Yankees may have favorable matchups this week against the Royals and Athletics rotations, but chances are, outside of two-catcher leagues, you can still do better than Martin.

With Adam Lind's batting average still south of the Mendoza line now six weeks into the season, the Blue Jays finally decided enough was enough Thursday, demoting him to Triple-A Las Vegas. General manager Alex Anthopoulos initially hoped the longtime starter would be able to return after the minimum 10 days, but reports of the Blue Jays placing Lind on outright waivers would seem to contradict that idea. He's looking plenty droppable in mixed leagues. Edwin Encarnacion will fill in at first base in Lind's absence, with the Blue Jays opting for a revolving door at DH. If Rajai Davis is part of that revolving door, his steals potential could make him a nifty pickup in Rotisserie leagues.

Worth a second look: Mark Trumbo, AngelsSuddenly, all that talk of Trumbo losing at-bats with Albert Pujols and Kendrys Morales on board this year seems kind of silly. He has started 17 of the team's last 18 games, displacing Peter Bourjos in the outfield rotation -- and for good reason. While Bourjos has struggled to hit .200, Trumbo is batting .414 (24 for 58) with three home runs and a 1.176 OPS over his last 16 games. With low-end hurlers like Tommy Milone, Graham Godfrey, Blake Beavan and Hector Noesi on tap for this week, the hot hitting should continue for Trumbo, making him practically a must-start in mixed leagues.Approach with caution: Carlos Pena, RaysSince his hot start, when seemingly everyone was buying into the idea that his return to Tampa Bay had rejuvenated him, Pena has hit a wall, batting .151 (16 for 106) over his last 30 games. That's a long time to be ice cold, but unfortunately for the career .238 hitter, it's par for the course. Pena will have another power surge at this point, but with Ricky Romero, Jon Lester and Josh Beckett among the pitchers on tap for the Rays, this week doesn't seem like the time.

The Padres have cut ties with veteran second baseman Orlando Hudson, instead opting to look toward the future. For now, that future is Alexi Amarista, who was one of two players acquired in the Ernesto Frieri deal. Amarista isn't considered a high-upside player, but he has some steals potential, making him worth a flier in NL-only Rotisserie leagues. The Giants have opted to go with a rookie at second base themselves, calling up Charlie Culberson on Sunday. Since then, the 23-year-old has gotten the majority of the starts over Emmanuel Burriss, generating some interests in NL-only leagues. Ultimately, though, his modest pop won't be enough to make him an impact player in Fantasy.

Worth a second look: Daniel Murphy, MetsGranted, Murphy hasn't seen a spike in power even with the fences coming in at Citi Field, but right now, he's hitting so well that he's a favorable mixed-league start anyway. He's batting .390 (23 for 59) over his last 15 games, and he's unlikely to slow down with three games against the Pirates pitching staff and four games against the Padres staff (away from PETCO Park, mind you) on tap.Approach with caution: Rickie Weeks, BrewersMaybe the red-hot Jonathan Lucroy will benefit from the Brewers' lefty-loaded schedule this week, but considering three of the six pitchers on tap are ace-caliber (Madison Bumgarner, Matt Cain and Ian Kennedy), the rest of the lineup might suffer. Weeks is already caught in a downward spiral, striking out at an unprecedented rate and collecting just six hits in his last 17 games for a .095 (6 for 63) batting average. Now that he's also dealing with a hand injury, sitting him is an easy call in mixed leagues.

After losing starts to Cody Ransom over the last few weeks (a move that some Fantasy owners probably wished would become permanent), Ryan Roberts has seemingly regained the trust of manager Kirk Gibson, starting eight of the last 10 games at third base. He's not so hot that you can pencil him in for another near 20-20 season, but the consistent at-bats are enough to make him an adequate fill-in at the injury-depleted third base position. Todd Frazier, who's replacing the injured Scott Rolen (shoulder) in Cincinnati, showed off his power stroke with a two-homer game Wednesday. His poor plate discipline may prevent him from being anything more than a stopgap option in Fantasy, but for now, he's worth monitoring in deeper leagues.

Worth a second look: Chase Headley, PadresHeadley hasn't offered much over the last few weeks, but the Padres only recently finished a 19-game stretch in which they played 16 home games. Considering he's a career .231 hitter at PETCO Park, you can understand why his numbers suffered. The Padres are on the road this week, however, and are one of a handful of teams playing a full seven games. Considering Headley is a career .301 hitter away from PETCO Park, now seems like a good time to reactivate him in mixed leagues.Approach with caution: Will Middlebrooks, Red SoxAs well as Middlebrooks has played during his time in the majors, all signs point to him going back to the minors when Kevin Youkilis (back) comes off the DL. And because Youkilis began a minor-league rehab assignment Wednesday, you can bet his return is just around the corner. You might only get a game or two from Middlebrooks this week, so as much as you've come to rely on him over the last couple weeks, go ahead and make a change.

Evan Longoria's injury has allowed Elliot Johnson to find some at-bats at shortstop, and he's made the most of them so far, showing enough speed, extra-base pop and on-base ability that you have to wonder if he might bump Sean Rodriguez out of the lineup when Longoria returns. He fizzled out after an early hot streak last year, so you wouldn't want to bet the farm on him, but if you need middle infield help, his stock is on the rise. Everth Cabrera's stock may be on the rise in the near future. He's the new starting shortstop in San Diego with Jason Bartlett (knee) on the DL, and he has big-time steals potential. He showed it with 25 steals over half a season as a rookie in 2009. If he can hit -- which is a big if -- he'll be a factor even in mixed leagues. Go ahead and take a flier on him if you're short on steals.

Worth a second look: Jhonny Peralta, TigersAs a whole, the Tigers lineup has shown some signs of life lately, so the hope is the hot hitting will spread to Peralta. If nothing else, his recent increase in walks (eight in his last seven games) shows he's seeing the ball better. The matchups certainly work in his favor this week, with the Tigers facing low-end hurlers like Ubaldo Jimenez, Zach McAllister, Justin Masterson, Jason Marquis and P.J. Walters. It's a complete shot in the dark given Peralta's lack of production so far, but at the weak shortstop position, some Fantasy owners are just that desperate.Approach with caution: Ian Desmond, NationalsUnlike Peralta, Desmond has actually been playing a little over his head lately, batting .294 (25 for 85) with four homers, three steals and an .844 OPS in May. He's still the same free-swinger who compiled a .656 OPS in 584 at-bats last year, though, so you shouldn't read too much into the hot streak if you're looking for a shortstop off the waiver wire. Chances are Desmond's matchups against Roy Halladay, Cole Hamels, Tim Hudson and Brandon Beachy this week will bring him back down to size.

The Giants made a change in right field all right, but Aubrey Huff, fresh off the DL, wasn't the one to replace the struggling Nate Schierholtz. Instead, journeyman Andres Blanco has been getting regular at-bats and carving out a niche for himself as the team's leadoff hitter. He has zero pop but legitimate on-base ability, and if he continues to hit like he has so far, his steals could make him a factor even in mixed leagues. His shaky track record makes him hardly a sure thing, but he has some sleeper appeal. Daniel Nava has a similar history and is off to an equally good start in Boston, bumping Marlon Byrd out of the lineup for now. He doesn't have a standout tool, though, which is why his time in the lineup might be short-lived. You can leave him for AL-only leagues.

Worth a second look: Mike Trout, Angels and Andy Dirks, TigersTrout is striking out about as often as you'd expect for a 20-year-old, but his minor-league numbers have translated otherwise. In fact, if anything, his power has been even better than expected at this stage of his career. With a .400 (20 for 50) batting average, three homers and three steals over his last 13 games, he's worth activating in mixed leagues, especially for a seven-game week against the Athletics and Mariners rotations. As for Dirks, he's been so hot over the last two weeks, batting .400 (22 for 55) with three homers and a 1.113 OPS in 14 games, that the Tigers have taken to playing him every day. He's still at his best against righties, though, and the Tigers face six of the most miserable in the league this week at Cleveland and at Minnesota. With that favorable forecast, Dirks is without question mixed-league material.Approach with caution: Bryce Harper, Nationals and Carlos Lee, AstrosHarper's home runs in back-to-back games Monday and Tuesday may renew the hype on him in mixed leagues, but keep in mind he went only 1 for 4 in both contests. He's still batting just .190 (11 for 58) over his last 15 games, enduring the kind of rough patch you'd expect for a 19-year-old. It might ultimately be short-lived, but with the Phillies and Braves pitching staffs on tap for the Nationals, you can probably do better than Harper in mixed leagues this week. The way Lee's power numbers have continued to evaporate this season -- he currently has a .779 OPS despite a .294 batting average -- you can probably do better than him most weeks. But chances are not even the singles will be coming his way this week, with Matt Garza, Jeff Samardzija, Clayton Kershaw, Chad Billingsley and Chris Capuano on tap.

Hendrickson was released by the Orioles a couple weeks ago after making four appearances in spring training. Hendrickson pitched in the majors for 10 seasons, posting a 58-74 record with a 5.03 ERA and 666 strikeouts in 1,169 innings.

(5:20 pm ET)Mike Olt is expected to be the Cubs' starting third baseman on Opening Day for a second straight year with the demotion of Kris Bryant to the minors. Even with the potential for Chicago to bring Bryant to the majors quickly, Olt is feeling confident heading into the 2015 season.

"It feels a lot different," Olt said of this season versus last year, per MLB.com. "I was able to go up there last year and learned a lot of things. I feel I'm back to the player who can really compete instead of the player who you hope is ready and you hope the swing is there. It's a lot different feeling, a lot less stressful."

Olt is having a decent spring at the plate, batting .279 with a .392 on-base percentage, .558 slugging percentage and .950 OPS in 19 games. It's a nice turnaround after batting .160 in 89 games in the majors last season.

"I had two crazy years and a lot of things happened to me," said Olt of some injury issues. "Now I feel it's in the past, and I have a new outlook on baseball and a new outlook on my career. I used to be one of those [top prospects like Bryant] -- and you forget about that. I feel myself becoming that guy again, and it makes baseball fun again."

"His intent is to hit," Black said. "He’s a very confident hitter, and when you think you can hit, you swing."

Pitchers exploited Gyorko's aggressiveness last season, and he struck out 100 times in 400 at-bats while hitting .210/.280/.333 with 10 home runs and 51 RBI. He hit better after spending nearly two months on the disabled list due to a plantar fasciitis. He focused on adding muscle this offseason.

"I went a little lighter last year in an attempt to get a little more flexibility," he said. "Obviously, it didn’t work, so I tried to beef back up. I tried to get as strong as I could coming into camp."

The team added plenty of offensive talent this offseason, and the team won't be forced to rely upon Gyorko to be a rock in the heart of the lineup this season.

"Unfairly, we probably put a lot of pressure on Jedd to be a guy in the middle of the order," Black said. “And I think he’ll eventually be a solid run producer there … I think another year of experience, being in amongst a group of (Justin) Upton and (Matt) Kemp, (Carlos) Quentin, whoever might be in the lineup, there will be a little bit of pressure off him to be the guy. I think guys like pressure. Guys want expectations. That’s what makes guys tick … Jedd has that. But when you have good players around you, it does put your mind at ease."

(5:05 pm ET)White Sox first baseman Adam LaRoche hasn't had a very good showing at the plate this spring, batting .186 with 14 strikeouts in 15 games. However, LaRoche said there is no cause for concern since his spring numbers never look pretty.

“My swing is one where it seems to take me the full spring training and some years past that to get it dialed in,’’ LaRoche said, per the Chicago Sun-Times. “I can remember only two or three springs where with a week left I felt really good.

“The good news is I’ve been there a lot, so there is no need to panic. It comes and goes here for a while. But I’ll be good.’’

Wainwright, who finished his final spring training start Tuesday, posted a 20-9 record in 2014 with a 2.38 ERA and 179 strikeouts in 227 innings. Wainwright dealt with a slight abdominal strain early in camp, capping him at just three starts in spring training.

(5:01 pm ET)Braves outfielder Melvin Upton Jr. is expecting to receive medical clearance on Friday to shed the protective boot on his injured left foot, according to the Atlanta Journal-Constitution.

Upton has been sidelined all spring with the injury. He had the hard cast removed from his injured left foot last week, and is expected to start the season on the 15-day disabled list.

"I've thrown a couple of times, lifting weights. Just waiting to get it off," he said. "It'll probably take a week to actually start really working on it again -- get in the shoe, start walking on it again. There's no timetable, but it'll probably be (when he's ready)."

(4:59 pm ET)Red Sox pitcher Wade Mileyconfirmed that he would be the fourth or fifth starter for the Red Sox to start the season.

Miley told the media he would make his first start of the regular season against the Yankees, although he didn't specify which game he would start. That series starts after three games against the Phillies.

That would indicate that Justin Masterson is the Red Sox's third starter, although manager John Farrell hasn't confirmed it.
